Use prescribed burning on shrublands
A before-and-after study in Artemisia spp. sagebrush habitat around the Idaho National Engineering Laboratory, Idaho, USA (Winter & Best 1985), found that in 1982 all 34 sage sparrow Amphispiza belli nests found were within sagebrush plants. In 1983, after a prescribed burn created a mosaic of burned and unburned patches, 23 of 29 nests (79%) were within sagebrush but six were in atypical locations: five on the ground under small plants and one within a grass clump.
